You're doing a few things that make your life hard (or are brittle) and
some that make things slow. Source the appropriate script for the intel
compiler that you want, and then leave MKL details up to it. Choosing -O2
for optimization overrides the defaults for no good reason. Thus

source /path/to/compiler/bin/compilervars.sh intel64
cmake ../ -DGMX_FFT_LIBRARY="mkl" -DGMX_GPU=on
-DCUDA_TOOLKIT_ROOT_DIR="/usr/local/cuda-9.1/"
-DCMAKE_CXX_COMPILER=icpc -DCMAKE_C_COMPILER=icc

It worths to say that the OS under current operation is Lubuntu (16.04)

On Linux, Intel compilers rely on having and finding a suitable gcc for the
standard library, so I can only presume something is messed up there. For
example, gcc was installed or updated after icc. Try the advice at
http://manual.gromacs.org/documentation/current/install-guide/index.html#compiler
